With the motto "Join the geeks", the IT One, the first platform for ICT decision-makers in Luxembourg, hosted coding enthusiasts to their hackathon "Game of Code" on 16 and 17 March 2018 in Luxembourg. Benefitting from the advice of technical experts and coaches, the teams had to tackle three coding challenges: Machine learning, Open Data Challenge, and Make@on. Participants had 24 hours to code, to discover new coding techniques, and to exchange knowledge with the competition from all over Europe. Accompanied by food trucks and video games, this event was one of the highlights of this year in terms of datathons. Here you find details on the event and the three challenges.
